I'm so sorry the information about Inversion was misleading when you placed your order.

When the package arrives, you can open and check the details, If the game was not as described, please return it for a full refund--including shipping costs. Because the return is a result of our error, we'll pay the return shipping costs, as well.

If there is anything else we can do to make things easier for you and to salvage what has up to now been a valued relationship, please let us know.

Technically, it looks like it has local co-op? The network options seems to include System Link, so you'll need two xboxes though. I guess that's how they get around it legally... So local co-op is yes, but no to split screen co-op.
